Well it Clemson’s from a fairly old event so pretty rare. It does have better stats than a normal one (not sure how big the difference is) and I don’t know if it’s breedable (probably not)

So you can compare it to the rareness of an event Pokémon within the past year I guess. Maybe a phione? Not sure
